(This is a dragon scale and can be brought to the Order of Dragonslayers in each Realm to be bartered for dragon treasure.)

Cannot be sold to merchants.

From the 12.15.09 Producers Note:
In this version we’re introducing Dragon Scales, a new type of alternate currency that drops off all of the dragons, including Goldestandt, Cuuldurach, Gjalpinvulva, Xanxicar, Nosdoden, Myrddraxis, and Draco, their minions. These Dragon Scales can be bartered for Draconic Stones, Dragon remains, and Dragon treasure. The Dragon’s aren’t exactly going to part with their scales easily, so would-be Dragon hunters beware!
